Scalar- quantity/amount that is expressed by a magnitude (numerical value) Distance- the amount of place covered
is the total length of path a moving object has traveled o Is a scalar quantity o speed Speed- distance traveled per unit time
Vector- quantities that are expressed by a magnitude and a direction. Displacement- How far out of place an object is
- involves both the measure of distance and direction traveled. o Is a vector quantity Velocity- is the speed in a particular direction
Friction - force between surfaces that resist the motion of one object or surfaces pass one another.
-force that opposes motion
- cause by the interlocking of the irregularities in the rubbing surfaces.
-always against the direction of motion
Force
- is a push or pull
Work
- force x displacement
Power
- work/time

Fulcrum - a point in which levers rests or is supported and on which it pivots.
Resistance Force
- is the force which an effort force must overcome in order to do work on an object
Load
- a thing which is heavy, and it is been carried out.
Applied force
- a force which is applied to an object by a person or another object
